The discussion centers on the use of non-conductive liquids, particularly distilled water, for electrical insulation at 230V. While distilled water is initially non-conductive, it can become conductive over time due to contamination and its polar nature, which allows for ionization when conductive materials are introduced. Transformer oil is recommended as a more suitable insulating liquid due to its stability and non-hygroscopic properties. Users also discuss various cooling methods for computer components, emphasizing the importance of using appropriate fluids that do not compromise electrical safety. Alternatives like mineral oil and propylene glycol are mentioned, with caution advised regarding their aggressive nature and suitability for electronics. Summary generated by the language model.
